Topic outline

  • Manufacturing Critical-Path Time (MCT)

    • MCT 1 - Welcome video topic of MCT

      In this video we explain the series of MCT videos and what to expect. MCT is the typical amount of calendar time from when a customer creates an order, through the critical-path, until the first piece of that order is delivered to the customer. MCT is part of Quick Response Manufacturing (QRM) developed by Rajan Suri. QRM is a method of controlling work flow in a high-variety, low-volume production environment and suitable, for both, manufacturing and office processes.

        
        

      MCT 2 - What is an MCT?

      This video discusses what MCT is and why is an important measure to use. MCT is the typical amount of calendar time from when a customer creates an order, through the critical-path, until the first piece of that order is delivered to the customer. An example is used to show the measurement principle. MCT is important because it can lead to improvements on reducing idle times and cost.

        
        

      This video shows how to draw an MCT map. You will learn what an MCT map is and how does it look like.  In addition, you will learn how to draw an MCT for simple straight forward production process and identify the total grey spaces (working time) and white spaces (idle time).

          
         

      MCT 4 - MCT Data Collection

      In this video we explain how you can collect date for the calculation of the MCT and use it to draw a MCT map. We will show you what kind of data you should collect. What is appropriate data? There are two important rules you should follow when performing the data collection. Lastly, alternatives to collect the data will be discussed.

        
        


      MCT 5 – MCT Calculation

      In this video we explain in more detail how to calculate the MCT.  At the end of this video, you will know all the basic metrics of MCT and how to calculate them.

        
        

      MCT 6 – Final Video

      In this video we provide a short recap of the MCT video series. MCT is the typical amount of calendar time from when a customer creates an order, through the critical-path, until the first piece of that order is delivered to the customer.

      MCT is one of the subjects within the overall topic of customized lean, within this topic you are introduced to many other tools to study the lead time of the production process.

        
        



      • Value Stream Mapping (VSM)

        VSM 1 – Introduction to Value Stream Mapping (VSM)

        Value stream is the series of activities that takes a product or service from the supplier to the customer. This applies, to both, physical products and administrative processes. The Value Stream Map is tool to illustrate the material flow, information flow and the value-added time.

        This first video explains the basics of VSM. You will learn why to use VSM map, when and how to use it.

          

          

        The second video will talk about the VSM map in more detail. You will learn to build a VSM map. It will explain the different symbols that are used and the steps to create this map. Finally, some tips will be given. 

          
          
        The third and final video presents a method to use VSM in production environments with High-Variation, Low-Volume products. This is especially valuable because a VSM is usually most effective in environments with a relatively stable product stream.

          
         


        • Service Blueprint

          Service Blueprint is a process mapping tool which is mainly used in service environments. It illustrates an in-depth customer journey applying a user centred perspective.

          This video presents the basic principles of the Service Blueprint.
